CORN PLANTER AND MARKER.

SPECIFICATION forming part of Letters Patent No. 440,917, dated November18, 1890.

Application filed August 25, 1890. Serial No. 362,918. (No model.)

To all whom it may concern.-

Be it known that I, JOHN DE BUTTS, a citizen of the United States,residing near Centreville, in the county of Queen Anne and State ofMaryland, have invented certain new and useful Improvements in CornPlanters and Markers; and I do hereby declare the following to be afull, clear, and exact descrip tion of the invention,such as will enableothers skilled in the art to which it appertains will not be covered bythe wheels, but will afford starting-points for the successive rows.This object I attain by providing a supplemental shaft which is throwninto and out of gear at will and operates devices for dropping chargesof the plaster outside of the lines of travel of the wheels. I also makeuse of certain additional novelties in the details of construction andcombination hereinafter particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a plan View of amachine embodying my invention. Fig. 2 represents a central verticallongitudinal section of the same 011 the line 00 no of Fig. 1, lookingtoward the operating gear-wheels. Fig. 3 represents a transverse sectionon the line y y of Fig. 1, looking forward.

- 00 w of Fig. 1.

A designates the axle; B, the main frame of the machine; 0, theseed-frame; D, the pole; E, the shoes; F, the seed-boxes; G, theseed-slide; H, the lever for operating said slide; J the shaft whichturns in bearings j Fig. 4 is a section on line.

to lock it in the position to which it is shifted; R R, thetransporting-wheels; S, the large gear-wheel turning with wheel R; T,the toothed segments on wheel M; U, the pinion on shaft J for gearingwith said segments; V, the locking-spring which presses its pin or stude into recesses u of said pinion, and W a flange raised on each segmentT and engaging a roller 10 on an arm of said spring V to raise stud vout of any one of these recesses.

All the devices thus far mentioned are substantially identical inconstruction and operation with the corresponding ones described in myaforesaid patent, No. 378,164, and reference is made thereto for afuller description and explanation of them.

X designates a pair of hoppers for plaster or other marking materialattached to the outer sides of the seed-boxes and discharging throughspouts or chutes :20 outside of the lines of travel of thetransporting-wheels R R. These chutes are provided with double cutoffvalves are, each pair being attached to a centrally-pivoted piece 02operating after the fashion of the similar devices which govern thepassage of shot in measured quantities from a shot-pouch. These pivotedpieces or small levers 00 are connected by long rods or pitmen X to theends of a double eccentric or double arm X on a shaft Z, which ismounted at one end in a bearing formed on a rigid arm 93 extendinglaterally from plate L. The other end of this shaft Z is journaled in alever Z, which is pivoted at its lower end to another lateral arm 00 ofsaid plate. The said shaft Z consists of a forward section ,2,longitudinally slot-ted at .2 near its rear end, and of a rear section 2which is connected to said forward section by a pin .2 passing throughholes in section 2 and also through the slot 2 of section ,2. Thismethod of attachment allows the said rear section to be moved by saidlever Z toward or from the plate L without disturbing the section 2. Thesaid lever Z moves in a slotted plate .2 which has shoulders .2 .2 forlocking said lever in either position to which it may be shifted. Thesection 2 is provided with a lateral arm or projection Y, which is inposition to be struck by a peripheral lug y of the segment (or one ofthe segments) T, when the said lever and shaft-section have been shiftedinto the position nearest to said plate L and the shafts thereon. Thestroke of this lug on the said arm Y will rock shaft Z in one direction,so as to let the charges of plaster fall, and a spring Y, surroundingsaid shaft and attached thereto at one end and to a relatively-fixedpart of plate L at the other end, then immediately rocks the said shaftin the reverse direction and closes the lower valves of theplaster-hopper chutes, while opening the upper valves so as to letadditional charges of plasterdescend as far asthe said lower valves,butno farther. When the lever Z is shifted to the other position, it movesthe said arm out of reach of said lug and the shaft Z of course does notrotate. The shaft Z and lever Z being wholly supported by plate L, theshifting of said plate laterally to cut off the seed-dropping devicesfrom the transporting-wheel R, as described in said patent, will ofcourse move said shaft Z and lever Z laterally also, and when the platemoves back toward said wheel all the parts attached to it move backalso.

The general operation ofthe improvements hereinbefore described is asfollows: In starting the first two rows of corn the lever Z is shiftedinto or allowed to remain in the position which leaves the shaft Zinactive, and it so continues until the end of the rows is nearlyreached. It is then shifted into the other position and allowed to dropthe plaster or other marking material a short distance beyond the lasthills of corn. In returning, these piles of plaster mark the point tobegin, and at the other end piles are dropped similarly for the samepurpose in repeating the forward movement across the field.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is-

1. In combination with the transportingwheels of a corn-planter andgearing driven by one of them, a shaft and connections for droppingplaster or other marking material at the end of the rows, said. shaftbeing pro- 3. The shaft Z, consisting of two sections 7 having a pivotedpinand-slot connection, rods or pitmen extending from one of saidsections to the plaster-droppingvalves, a lever attached to the othersection of said shaft for shifting it laterally, an arm carried by thelatter section, a toothed segment having a peripheral lug on its rearend for operating said arm, a set of corn-dropping devices operated bysaid segment, a transporting-wheel R, and the necessary interveninggearing, substantially as set forth.

4. In combination with the transportingwheel R and gearing operatedthereby, a toothed segment forming part of said gearing and providedwith a lugnear its rear end, a shaft Z, having an arm arranged to bestruck by said lug at intervals for rocking said shaft, and aretracting-spring which turns said shaft in the opposite direction, thesaid shaft consisting of two sections arranged end to end and pivotedtogether, one of them being provided with a lever for shifting itlaterally, as described, and the other section left stationary,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JNO. DE BUTTS.
